Miniature stereoamplifier
Dokulil, Zdeněk ; Mišurec, Jiří (referee) ; Káňa, Ladislav (advisor)
The aim of this thesis was to design and construct a mains powered stereo power amplifier with minimal overall dimensions, equipped with a mute and tone/volume control circuit. The usage of an integrated power amplifier circuit was required. The circuit solution is based on a DC controlled integrated tone and volume control circuit LM1036, power amplifier TDA7262 and a number of supporting circuits for mute switching and temperature protection. An assembled sample of amplifier has 2 x 20 watts of output power, SNR 83,7 dB and a flat frequency response within the range of 3 dB for inputs from 16 to 20 000 Hz.

Analog distortion musical signals
Růžička, Matěj ; Kubánek, David (referee) ; Vrba, Kamil (advisor)
In this bachelor thesis I studied the differences in sound of valve amplifiers and solidstate amplifiers, causes of those differences, mathematical modelling the transfer characteristic of valve amplifier and then modeling it with simple diode limiter, which used several types of semiconductor diodes, Properties of those diodes were measured as well. Then I constructed limiters for both polarities of input signal, which had non-linear transfer characteristics similar to the valve amplifier and I evaluated their qualities. Then I measured simple amplifier with bipolar transistor, JFET N-channel transistor and optocoupler, Furthermore, I modified triangle-to-sine converters with bipolar transistor, JFET N-channel transistor, measured and evaluated their transfer characteristics. At the end of this bachelor thesis I described designing a diode-based functional converter and converter made from several bipolar transistors, both of these had similar shape of transfer characteristics and I evaluated their qualities by comparing weighted harmonic distortion of the output signal with output signal of tube amplifier.

Campaign Finance in the U.S. : McCain-Feingold Reform
Vydra, Pavel ; Sehnálková, Jana (advisor) ; Calda, Miloš (referee)
The United States has a long history of political campaigns. The Bipartizan Campaign Reform Act of 2002, also known as McCain-Feingold, was the last attempt to regulate the campaign finance. Being enacted in order to cover the loopholes that occurred in the Federal Election Campaign Act, this act banned the "soft money", it modified the rules for the pre- electional broadcasting, and it brought special restrictions for self-financing candidates. These changes succeeded to be enacted by both chambers of Congress, were signed by the President and upheld by the Supreme Court in the McConnell v. FEC landmark decision. However, the impact of the reform didn't quite meet the expectations of its supporters.

Limitations of actions as a legal fact
Paulů, Marek ; Hendrychová, Michaela (advisor) ; Šustek, Petr (referee)
Limitation as a legal fact Legal institute of limitation has been a part of the legal system since the days of Roman law, yet it is not a legal relic, which in the modern concept of rights had their place. Limitation is a legal institute that is an integral part of modern legislation and whose meaning in law is a proven tradition of more than fifteen hundred years. The aim of this thesis is to give a comprehensive explanation about the institute of limitation in civil law. This thesis divided into five chapters approaches the status of limitation among other legal facts, subjecting it to a thorough analysis, gives the view on the concept of limitation de lege lata and its evolution in our country through historic civil law codification and compares its approach with adjustments in selected European countries. The first chapter discusses general information about legal facts which are divided by traditional keys and on the basis of this division and between them rest the institute of limitation. The second chapter defines the concept of limitation, refers to its meaning, analyzes its components, tests subjects objection of forfeiture accordance with good manners, calculates the rights that are subject to limitation and states that are contrary legislature declared inviolable. This chapter also...

Unjust enrichment under business law
Keltner, Miloslav ; Horáček, Vít (advisor) ; Rozehnal, Aleš (referee)
Unjust enrichment under business law The aim of this work is to analyze the unjust enrichment with its overlap to commercial law. The introduction of the text summarizes the historical development of unjust enrichment from ancient Roman law provisions, including the Austrian General Civil Code and the Civil Code from 1950 up to the history of the currently effective codex published under no. 40/1964 Coll. This historical analysis points out certain analogies with the current regulation and the development of elements that are the foundation of today's unjust enrichment legislation. The following part of the work contains analysis of the current de lege lata legislation of unjust enrichment in the commercial law, the subsequent part constitutes the crucial part of this work that is concerned directly with unjust enrichment in the commercial law. First, it analyses the term of business contractual obligations, then it analyses the relationship between the Civil Code and the Commercial Code and finally it sums up the expert discussion relating to the unjust enrichment in the commercial law and subsequently the author presents his personal view of the problem and the effects of the unjust enrichment, especially on the question of limitation period, are considered briefly. The final chapter consists...

Piala, Zuzana ; Žikovská, Petra (advisor) ; Křesťanová, Veronika (referee)
Limitations to copyright protection of computer programs The topic of this work is the limitations to copyright protection of computer programs. The first chapter explains the basic terms of computer science, which shall help the reader to orientate in this issue. These are terms as computer program, software, source code and machine code and graphical user interface. The chapter draws attention to lack of the legal definition of a computer program in Czech law, the difference between software and computer program is explained and the individual categories of software are introduced herein. After this introductory chapter, the second chapter provides an overview of the basic sources of software law. First it presents the international agreements by which the Czech Republic is bound as the Berne Convention, the TRIPS agreement, the WCT agreement and Convention on Cybercrime. It also focuses on the regional area of the EU and analyzes the Information Directive and the Software Directive. Subsequently, the text deals in detail with the conditions of copyright protection in the Czech Republic and its specifics. Thus, the work provides a theoretical basis for the following chapters, which present more complex issues in this area. The third chapter deals with the general limitations to copyright, which...

Schweiner, Petr ; Staša, Josef (advisor) ; Rajchl, Jiří (referee)
Some disfranchisement and limitation of property rights of immovable things in Czech administrative law Summary nThis work deal with some disfranchisement and limitation of property rights of immovable things in Czech administrative law. The work have three main points of interest. First point is discribtion substantive conditions disfranchisement and limitation of property rights. I analyze difference between limitation property according to Art. 11 para. 3 and Art. 11 para. 4 of the Charter of Fundamental Rights and Freedoms. It was made "algoritmus intenzity" "the algorithm of intensity" for this diferenciace. There is discribtion substantive conditions of disfranchisement and limitation of property rights according to Art. 11 para. 4: "in public interest under the rule of law and with compensation.", according to Art. 11 para. 3: "under the rule of law, proportionality, general interest" and loock for difference of disfranchisement and limitation of property rights in international documents for example the European Convention for the Protection of Human Rights and Fundamental Freedoms from 1950. Specially the First Protocol to the European Convention, signed in Paris in 1952, includes the right to the peaceful enjoyment of possesion in the Article 1 which are Very important for Czech regulation For...
